UNITED STATES PATENT OFFICE.

WASHINGTON DEW OF CHICAGO, ILLINOIS- KEY-FASTENER.

SPECIFICATION forming part of Letters Patent No. 281,247, dated July 17, 1883.

Application filed August 31, 1882. (No model.)

To aZZ whom it may concern;-

Be it known that I, AsHINGToN DEWEY, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Key-Fasteners, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is a perspective View of a key-fastener embodying my invention, and showing the same applied and re taining the key in position when the door is locked. Fig. 2 is a side view of the fastening detached; and Fig. 3 is a like representation, showing a modification of a part of the same.

Like letters of reference indicate like parts.

A represents the door, and B the lock, the bolt being shown at a and the catch at a. C is the escutcheon. D is the door-knob; E, the rosette, and F is the neck or spindle of the knob. G is the key. H is the key-fastener. This fastener consists of the stock or horizontal part b of the hook c, hook-shaped on its lower end, and vertically adjustable in the stock I), of the tightening-screw d, arranged to clamp or hold the hook c in the position in which it may be set, or adjusted, and of the vertical hanger e, applied to the stock I), and projecting upward therefrom. The upper end of the hook c is slightly enlarged or headed, by preference, to prevent it from falling through or out of the stock 6 when the screw cl is loosened, as shown.

To apply the fastener H for use, I hang the hanger 0 upon the neck F. I then hook the hook into the key after the latter has been turned to lock the door, the screw (1 being loosened for the purpose of allowing the hook e to be moved vertically in the stock (2. I then push up the hook c as far as the key will permit, and then tighten the screw (1 firmly. By this means the key will be firmly held in the door in such a position as to keep it locked, it being understood that the key, before being engaged by the hook c, is to be turned as far as possible in the direction required for looking the door. The key is also thus prevented from being pushed out of the door from the outside, and also from being manipulated by means of tools applied from the outside. The key, however, may be very easily released by loosening the screw d, and the fastener may then be removed, or else allowed to hang upon the neck F without engaging the key. When the fastener is removed, it may be carried upon a key-ring by hooking the hook 0 into the ring, raising the said hook to its highest position, and tightening the screw d.

It may sometimes be expedientas in hotels or other public places-to provide means for preventing the fastener from being removed from the door with facility. This I accomplish by bending the upper end of the hanger 6 into the form of a ring adapted to receive the neck F. When the hanger e is so formed, I apply the fastener by removing the knob I), passing the neck F through the said ring, and then applying the knob to the door in the usual manner.

This fastener is very simple in its construction and operation, is light, compact, strong, and may be easily applied to various doors.

I am aware that a bow-shaped wire adapted to hang from the knob-spindle and to pass through the key-loop has heretofore been coin bined with a block which received the arms of the said how, and which carried a set-screw, and I do not here intend to claim the same; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

' A key-fastener consisting of the stock I),

arranged horizontally and having a screwthreaded opening in one end, the key-hook c, passing vertically and freely through the stock I the vertical hanger e, applied rigidly to the said stock, and the set-screw d, entering the screwthreaded opening in the stock, and adapted and arranged for contact with the hook c, to retain the latter adjustably in the stock, substantially as and for the purposes specified.
